SPECTACLESY.

SPECIFICATION forming part of Letters Patent No. 771,067, datedSeptember 27, 1904. Application filed eptember 21, 1903. Serial No.174,087- (No model.)

To all whom it ntcty concern:

Be it known that I, HABBO HEEREN, a subject of the Emperor of Germany,residing in the city of l-lameln, in the Province of Hanover, Germany,have invented certain new and useful Improvements in Spectacles, ofwhich the following is a full, clear, and exact specification.

My invention relates to the construction of spectacle-frames; and itconsists of thehereinafter-described improvement in the construction ofsuch frames, whereby the lenses are,

made axially movable for the purpose, so they may be set in suchposition relatively to the eyes and to the .object viewed that the lineof vision will pass through the center of the lenses in whateverposition the eye may be required to be raised or lowered to view theobject.

My invention is illustrated in the accompanying drawings, Wherein Figure1 is a detail plan View, and Fig. 2 a side view, of the joint forconnecting the rim of the lenses or the bracket holding the lenses withthe temples. Fig. 3 is an elevation of the pivot for connecting theconnector with the joint of the rim or bracket holding the lenses, andFig. 4 is an isometric view of rimmed spectacles provided with myimprovement.

In the drawings, a designates the rim wherein the lenses 6 are set.

0 designates the temples for holding the spectacles in position in frontof the eyes and which may have their ends tapered or curved, as shown inF ig- 4, or may be straight or of any other form.

f is the connector, forming the connection between the temples c and therim (6. This connector f is in the form of a U-shaped spring, beingbifurcated on the end connected with pivot g. (Shown in Fig. 3 inenlarged detail.) This pivot is preferably an integral part of the rim,(or of the brackets when the lenses are not set in a rim.) This pivot issnugly fitted into the bores it of the prongs of connector f and isscrew-threaded on its end, so that the connector may be secured thereonby screw-nut z'. This nut serves also for producing the necessarytension upon the connector. This tension is produced by compressing theprongs f and f of the connector f between the head g of the pivot g andthe screw-nut For better convenience washers may be inserted, one toeach side of the connector f, as shown in the drawings; but they are notessential for the proper operation of the device. Instead of thescrew-nut i a rivethead may be formed on the end of the pivot g afterthe connector is slid thereon. The other end of the connector f isrecessed or bifurcated at right angles to the slot between the prongs fand f and rounded. A bore k is provided therein at right angles to theslot or recess, and the temples c are fitted into the slot or recess andhinged thereto in the usual way. The position of these parts could bechanged. By that I mean to say that instead of pivoting the connectorsto the rim of the spectacles the socket could be hinged thereto andpivoted to the ends of the temples; but the form describedto wit, thepivoting of the connector to the rim or brackets of the lenses andhinging them to the templesis preferable and much more effective.

Spectacles provided with the improvement, as herein shown and described,permit the turning of the lenses while the spectacles are set inposition in front of the eyes, so that, for instance, a person readingin a sitting position and desiring to view objects on a level with hiseyes or higher may so turn the supports of the lenses as to bring themimmediately in alinement with the axis of his eyes, or a person walkingand desiring to view an object on the ground may by the simple turn 4 ofthe supports of the lenses adjust the same properly in the line of thevision.

My improved spectacles will be found advantageous for hunters orsharpshooters when compelled to aim in lying position. The capability ofadjustment of the lenses will enable such hunters or sharpshooter-s toaim at the object through the centers of the lenses without undulystraining the muscles of their neck, and at the same time it will avoidthe missing of the object, which is due to a refraction of thevision-line, and often happens in such cases when eyeglasses orspectacles are used constructed as heretofore and which do not permit ofsuch an adjustment.

1 claim as my invention 1. The combination, with the supports for thelenses of spectacles, of connectors pivoted to the supports whereby theyare rotatable in a plane transverse to the axis of the lens, templeshinged to the connectors, and means independent of the templehinge-joints for producing spring tension upon the said pivotal jointsof the connectors.

2. In a spectacle-frame, the combination with the lens-supports, of apivot extending outward from the supports at a right angle to the axisof the lenses, a pair of U-shaped resilient members having apertures intheir arms at which portions they are rotatable on said pivots,fastening means on the pivots arranged to retain said members underspring tension whereby a resistance is offered to its rotation on thepivot, and a temple hinged to each U- shaped member.

3. In a spectacle-frame, the combination with the lens-supports, of apivot extending outward from each support at a right angle to the axisof the lens, a pair of socket members each having a forked springportion containing apertures, said pivots each having one of the socketmembers rotatable thereon at said apertured portion, a nut on each pivotsecuring the sockets on the pivots under spring tension wherebyresistance is offered to the rotation of said member on the pivot, and atemple hinged to each U-shaped member.

4. In a spectacle-frame, the combination with the lens-supports, of apivot extending outward from each lens at a right angle to the axis ofthe supports, a pair of socket members each having a slot at one end, atemple pivoted in each said slot, the socket members each having aforked spring portion containing apertures, said pivots each having oneof the socket members rotatable thereon at the said forked portion, anda nut on the end of each pivot securing the sockets on the pivots withthe forked portions under tension whereby resistance is ofi'ered to therotation of said member on the pivot.

HABBO HEEREN.
